Oil all over the road! HELP!

[mtcs]

Hey,
Got my car back from Hybrid connection (DSM shop in NY) on Friday and apparently right before I got there to pick her up, the O-Ring in the oil filter came loose and spewed oil all over the motor. Caused some burning action on the oil filer and oil return lines. They fixed it and a few hours later I came by and picked the car up.
Two days later, I think the same thing happened. I was driving doing like 50 or 60 and all of a sudden my oil pressure shoots down to 0psi. I stopped the car and looked behind me and there was oil all over the road. I let the car cool down then looked under the hood and saw that there was oil spewed all over the right side of the bay.
It was way too late (2AM) to wait for AAA to come tow me so I just left it on the side of the road until the morning (8AM).
My question is, what could be causing the oil filer o-ring to mess up so bad? I think I am just going to get it towed back to hybrid connection and let them see what’s up.

Anyone have any idea why it would be breaking and spewing everywhere?

I did 491/500 miles that I had to do on the motor break in period. At 500 miles I had to change the oil, looks like it changed the oil on its own.

Thanks to Gary Burch of Hybrid connection, looks like he caught the problem.

"The water cooled oil filter housings suck. Many...many engines have been trashed by this cooler. Jordans car started on fire because of it blowing out the same oil filter o-ring. Tevenor's oil filter housing actually came loose from the block and lost all oil. A customer of ours Dan Cook almost had the same tragedy that Tevenor had but we caught it just in the nick of time. Your car blew the filter o-ring once for sure...maybe even twice now.

My theory is that the since this oil cooler section has cooler passages and thin metal that it collapses enough for the high oil pressure of a non-balance shafted engine to find a weak spot which appears to be the o-ring. I think the 75-100+ oil pressure is just so great between the oring and cooler that it actually collapses the cooler enoungh to push the o-ring past the bead and therefore loose all oil pressure. This would have been even more of a problem if we did not port your oil cooler housing relief valve to allow no more than 100psi oil pressure.

When your car gets to the shop we will let you know what really happened. Plus as usual you are doing the right thing and going with the 1990 style oil to air cooled housing which to my knowledge has never had this problem and hence why the evo7-9 whent back to this design.

As of right now we will no longer build 6bolts with the water cooled housing. It is too much of a strain on the radiator cooling system and just not worth a car fire, blown engine, or death."

Thanks Gary!

as simple as this might sound, i had the EXACT same problem, it could be the filter screw, you'll dump your oil, put a new filter on and it'll seal and hold on for a bit, then do the same thing. it turned out to be the little screw that the oil filter screws onto was loose, pull the oil filter and try to turn the screw, if its the problem it will be easy to turn, if not it was a easy thing to check before pulling the oil pump housing
